E36 Dash Cluster interfacing using a microcontroller Hey guys, Just wanted to let you know what sort of signals the dash cluster is expecting. These things are getting popular with the racing emulator crowd - tons of info available for hooking up to it, but I am going to discuss attaching to the cluster and engine RPM signal. I struggled to accumulate all this info so I am hoping this will help to anyone who may need this kind of info in the future. This is the beginning of the thread and I will post detailed diagrams, microcontroller code, and info on all of the parts I used and all the info that one may need to get a signal appropriately modified to your liking. Cheers, Artem |
